2 Claims. (CI. 2473) This invention relates to slide loops of a type adapted for rapid and easy strap insertion and more particularly introducing into the art a novel type of wire slide loop into which a strap is inserted and secured without any off-set or hump whatsoever and thus maintained throughout its 'full length of contact with the slide loop in perfect parallel relation to the general plane of the slide loop.

The objects of the invention therefore are to provide a wire slide loop with an integral straploop having a strap-passage of opposing and passage confining wall structure of which both the structure and the passage lie parallel to the general plane of the slide loop; to provide for such a slide loop a sheet-metal hinged member integrally carrying a strap-binding element up into the strap-passage to bind an inserted strap against a wall of said passage; and to provide for such hinged member a stop-lift also integral therewith.

In the accompanying drawing the Figure 1 is an upright front view of the improved slide loop in strap-receptive position; Figure 2 is a side view of the slide loop with an unsecured It inserted strap; Figure 3 is an upright front View of the improved slide loop in strap-securing position; and Figure 4 is a side view of the slide loop showing an inserted strap secured therein.

The applicant is aware that, outside of the field of wire structure, there are sheet-metal structures providing housings for a vertical strappassage therethrough from overhead but, notwithstanding such disclosures in the art, the novelty herein claimed relates particularly to slide loops comprising in part a wire button loop of which the backwardly bent strap-suspension loop, providing as it does the strap-passage for overhead insertion of a strap which in its entire association with the slide loop lies in a parallel plane thereto, is an integral part of the wire structure.

With particular reference to the drawing, the numeral l designates a wire button-loop having a face 2 and being of a type generally known to the art and comprising in part a strap-suspension loop 3 having the upper bar 4 and the spaced lower aligned bars 5, but in the utilization of the buttom-loop l in the construction of the improved slide loop, the suspension-loop 3 is bent rearwardly away from the face 2 and at an angle therewith into a plane substantially transverse to that of the main portion of the button-loop l, and the bar 4 is provided with spaced depending loops 6 providing a wall surface *3 opposing a wall surface I of said main portion of the button-loop I which wall surfaces 6 and I, together with saidbent loop 3, define a straight strap-passage 1 parallel to said main portion of the button-loop l.

Hinged to the spaced aligned lower bars5is the sheet-metal member 8 movably. connecting the aligned. bars 5, as at 9,.thereby leavingthe integral'depending arms of the britton-loop 1 free for a relative and limited movement'in the button-loop plane. Integrally carried by the sheet-metal member 8 are the strap-binding elements it together swingable, upon the movement of the hinged member 8, up into the strappassage I in close proximity to the wall surface 5' of the loops 6.

If desired the engaging edges of the binding elements It! may be provided with teeth.

Also integrally carried by the sheet-metal member 8 is the stop-lift l l engageable with the face 2 of the button-loop l as the strap-binding elements It are fully swung into strap-binding position within the passage 1.

In operation, the slide loop parts are first so relatively positioned that, as illustrated by the Figures 1 and 2, the strap-passage 1, defined by the opposing wall surfaces l and 6', is free and open to permit the direct insertion from above of a strap l2 therein, as illustrated by the Figure 2. With the strap [2 within the passage 1 the stop-lift I i is manually swung downwardly upon the face 2 of the button-loop I so that by this operation of the stop-lift H the strap-binding elements it are swung up and into the passage 1 to engage the inserted strap I2, thereby binding and crowding the strap l2 against the wall surface t but arrested from farther advanced movement within the passage 1 by the said engagement of the stop-lift H with the face 2 of the button-loop I.

For the purpose of adjustment of the slide loop along the length of the strap IE, or for permanently releasing the slide loop therefrom, the stop-lift ll may be manually lifted away from the face 2 of the button-loop l to reverse the movement of the binding elements it) and thereby open up the passage i through which the strap 52 may be moved or withdrawn.

It will be noted that, in the crowding and binding engagement of the binding elements II! with the strap l2 inserted within the passage 1 in their full engagement limited only by the stop lift II, the elements iii are permitted to swing slightly past and up out of a right-angled plane to that of the general plane of the slide loop. To attain such a binding position the binding-elements l must be urged, by means of the stop-lift ll, past the center of its contact with the strap I'Z against the Wall surface 6 of the depending loops, 6. The return of the binding elements I0 past its center of contact is possible only by means of an initial urge in lifting the stop-lift ll away from the face 2 of the button-loop part of the slide loop. It is clear therefore that all upward strain upon a taut strap l2 tends only to maintain the strap-binding grip by the binding elements 10.

The outstanding advantages in the use of the improved wire slide loop is in the full elimination of the hump of strap material usually present in the threading of a strap into the slide portion of a slide loop, and also the simplifying of the process of attaching and adjusting a slide loop with relation to a strap with which it is associated.

Iclaim:

1. A slide loop comprising a wire structure of whicha portion lies in one plane; a strap-receiving loop integral with said structure but rearwardly inclined with respect to said plane; parallel outer bar and aligned bar portions with which the strap loop is provided; depending formations with which the outer bar is provided;

said formations being disposed spacedly parallel tosaid plane; and a sheet-metal member hinged upon said aligned bars and having a part carried by said member adapted to be urged into engagement with said formations to thereby clamp a strap inserted within the strap loop therebetween so that the strap thus clamped may retain its parallel relation to said plane throughout its inserted length.

2. A slide loop comprising a wire structure comprising button receiving and retaining loops in a common plane; a strap-receiving loop integral with said loops but rearwardly inclined with respect to said plane; parallel outer bar and aligned bar portions with which the strap loop is provided; depending formations with which said outer bar is provided, said formations being disposed spacedly parallel to said plane; and a sheet-metal member hinged upon said aligned bar portions, said member including a stop-lift and jaw portions relatively extending at an angle, one from the other, from the hinged portion so that as the stop-lift is made to engage the button receiving loop structure said jaws assume a swung position within the strap loop and against said depending formations, whereby a strap inserted within said loop may be positively held therein clamped between said depending formations and said jaw portions and thus clamped retain its parallel relation to said plane throughout its inserted length.
